JPG to PNG online
Convert a JPG image to PNG in your browser — for when the next step in your workflow needs lossless pixels or a format that supports transparency downstream.
How to use this tool
- Choose the JPG image.
- Click Convert. The image is decoded and re-encoded as PNG locally.
- Download the PNG from the result.
Common uses
Preparing an image for editing steps that would compound JPEG artifacts, feeding a tool that only accepts PNG, turning a photo into a pixel-exact intermediate for compositing, and screenshots pipelines that standardise on PNG.
How it works
The conversion decodes the JPEG to pixels and writes those pixels as PNG. Two honest consequences: the file usually gets bigger, often several times, because PNG's lossless compression cannot match JPEG's lossy tricks on photographic content; and no quality comes back — the JPEG artifacts already in the image are preserved faithfully, pixel for pixel, rather than removed. What you gain is a lossless container: further edits, crops and re-saves of the PNG will not degrade it further, and the format can carry transparency if later steps add it.
Worked example
A 2400×1600 photo at 480 KB as JPEG typically lands between 3 and 5 MB as PNG — same picture, ten times the bytes, zero additional detail. That trade is right for an editing intermediate and wrong for a web page: if the destination is a browser, the Image Compressor or WebP Converter on this site serves you better.
Privacy and browser processing
Your image is converted in your browser on a local canvas — it is never uploaded or stored.
Frequently asked questions
Will the PNG look better than the JPG?
No. It will look identical — the conversion preserves the decoded pixels exactly, including any JPEG compression artifacts. PNG stops future losses; it cannot undo past ones.
Why is the PNG so much larger?
JPEG throws away visual information mathematically tuned to be unnoticeable in photos; PNG must store every pixel losslessly. On photographic content that difference is routinely 5–10×. On flat graphics and text, PNG is often smaller — content decides.
Does the PNG have transparency?
Only if the pixels do — a JPEG has no alpha channel, so the converted PNG is fully opaque. Transparency can be added by later editing, which is often the real reason for the conversion.
When is this conversion the wrong tool?
For publishing photos on the web (stay JPEG or move to WebP), and for "restoring" quality (impossible). It shines as an intermediate format and for format-requirement situations.
Is my image uploaded?
No. Conversion happens on a canvas in your browser; the image never leaves your device.
